Welcome to the ZNC wiki where you may find and publish information about ZNC, an advanced IRC bouncer that is left connected so an IRC client can disconnect/reconnect without losing the chat session. Feel free to update pages which you think are improvable and don't hesitate to ask for help.

ZNC will remain connected to IRC even while you are offline. You can then reattach later and catch up with what happened while you were gone, and your nick (and operator status) will have been kept for you.

Multiple Users

You can add additional users under one running process. Useful for public shells that limit background processes.

Multiple Networks

Each user can connect to several IRC networks at once, with an optional limit configured by ZNC admin.

Multiple Clients

Connect to the same user/network with as many clients as you want.

Playback Buffers

Stay up-to-date with what happened and when it happened while you were detached, timestamps are also printed and can be manually configured.

SSL Support

Encryption for both the listen port and connecting to IRC servers. If your system has OpenSSL, ZNC automatically supports SSL connections.

IPv6 Support

Both IPv4 and IPv6 address families just work, if your system supports them.

Partyline

Using the global partyline module, you can join channels and query users on the internal ZNC network

Web Administration

Using the global webadmin module, admins can add/remove/edit users and global settings and non admins can edit their own user settings.
